ROLLING-MILL-OPERATING- MECHANISM.

Specification of Letters Patent.

Patented Oct. 8, 19-18.

Application filed March 15, 1918. Serial No. 222,581.

To all whom it may concern:

Be it'known that I, GEORGE E. DAY, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Rolling-Mill- Opcrating Mechanism, of which the followin% is a full, clear, and exact description.

his invention is an improvement in the driving mechanism for a plurality of stands of alined rolls for rolling structural iron and the l ke. The object is to provide drivin mechanism operableby asingle motor by means of which all of the rolls may be driven when all are required, but whereby, when any stand of rolls is put out of commission for any reason, all of the other stands of rolls may be continued in operation.-

The invention consists in the construction and combination of parts shown in the drawing, hereinafter described and definitely pointed out in the appended claims.

In the drawings, Figure 1' is a plan view, Fig. 2 is an elevation of a four-stand rolling mill equipped with this invention; and Fig. 3 is a vertical section through a pinion housing. 4

In the' embodiment of the invention shown there are four three-high stands 10, 11, .12, 13, or rolls set side by side with the corresponding rolls of the four stands in substantial alinement. The corresponding, 6. 6., substantially alined rolls of the four stands, are operatively connected by coup'ling sleeves 14 and spindles 15 of well nown construction.

Each of the two outsidestands 10 and lfi is associated with a pinion housing 16. In each pinion housing are mounted three shafts 20, 21, 22, in substantial aline ment with the three rolls in the adjacent stand,

and each of these shafts is connected with the adjacent substantially aiied roll by means of coupling sleeves l4 and a spindle 15 substantially as before explained.

Nithin the pinion housings are pinions 23 secured respectively to said shafts, and in mesh'with each other. One of the three spindle shafts-it matters not which oneextends out of the housin and its projecting outer end is operative y connected with a gear, preferably by aspindle 1 5, and cdupling sleeves 14, which engage with the spindle and with the projecting pinion shaft, and a shaft 31 which carries said gear 30. These two gears 30 respectively mesh with gears32 and fixed to the driving shaft 34 which extends transversely with respect to the stands of rolls, and from one side of the group to the other. A single motor is employed to drive this shaft.

Under normal conditions, that is to say, when all of the stands of rolls are capable of beinoused, and the use thereof is de sired, there is a dual drivin; connection, that is to say, the rolls are driven from hot h sides of the group through the gears 30, the pinions in the two pinion housings. and the coupling sleeves and spindles. If. however, it is desired to cut out one stand of rolls either because it is not required for the work being done, or because something about it r'cquires repairing. the rolls of that stand are uncoupled from the rolls ,of the stands on opposite sides thereof. or from the rolls on one side and pinion shafts on the other. In that event, the remaining rolls will be driven by the described mechanism, that is to say. all of the rolls on one side of the so cut out stand will be driven from the pinion housing: that side of the group, and all of the rolls on the opposite side of the cut out stand will be driven through the pinion housing on the other side of the group. \Vhcn it is desired to put into commission the stand of rolls temporarily in disuse one merely couples the ends of thc rolls by the described coupling mechanisms with the rolls on either sidethereof.

Having described. my invention. 1 claim 1. In a multiple stand rolling mill, the comb ination of a plurality of stands of rolls sot sre-by side with the corresponding rolls 'of the sevenal stands in substantial alinement, means for connecting and disconnecting the ad]acent ends of the almed rolls,

two pinion housings respectively located e1dj-acent the outside stands of the group of stands of rolls, pinion shafts mounted in each pinion htmsinp in substantial alinement with the adjacent rolls, coupling devices for connecting, the adjacent ends of said pinion shafts and alined rolls, intermeshing pinions secured to said pinion shafts, a single motor, a shaft driven therepinion housings respectively located adja-.

cent the outside stands of the groupof stands of rolls, pinion shafts mounted in each pinion housing in substantial alinement with the adjacent rolls, coupling devices for connecting the adjacent ends of said pinion shafts and alined rolls, intermeshing pinlons secured a to said pinion shafts, and

' means by which to drive the pinions in both housings at the same rate.

3. In a multiple stand rolling mill, thecombination of a pluralitv of stands of rolls set side by side with the corresponding: rolls of the several stands in substantial alinement. means for connecting and disconnecting the'adjacent ends of alined rolls. two pinion housings respectively located adjacent the outside stands of the group of stands .of rolls, pinion shafts mounted in each pinion housing in substantial alinement with the adjacent rolls, coupling devices for connecting said pinion shafts with the alined rolls, intermeshing pinions secured to said shafts, one of said shafts being projected out from each pinion housing, a gear coupled to the projecting end of each of said pinion shafts, and asingle transversely extended driving shaft, gears thereon in constant mesh with the gears coupled to the projecting end of the pinion shafts, and a single motor foidriving said driving shaft.

In testimony whereof, I hereunto atlix my signature.

GEORGE E. DAY.
